热阴极20瓦直流黑光灯具有亮度大、诱虫多、使用灵活方便、适于山陇田大面积诱杀害虫和无须市电做电源等优点,深受广大贫下中农欢迎。但是“事物都是一分为二的”,它还存在着稳定性差及灯管容易早期发黑报废等缺点,影响了它的推广应用,广大贫下中农迫切要求尽快解决这些问题。今年,我们坚决执行毛主席的无产阶级教育革命路线,走出校门,与贫下中农共同试验,从黑光灯发光的物理原理分析了不稳定和灯管早期发黑的原因及内在联系,找出解决问题的关键,提出了从变流器线路上进行改进的方法,其线路如图2所示。改进后的变流器,灯管工作累计达2000多小
Hot cathode 20-watt DC black light with large brightness, attract more insects, the use of flexible and convenient, suitable for a large area of mountain Longtian trap insects and electricity do not have the advantages of electricity, welcomed by the majority of poor farmers. However, “things are divided into two parts.” There are still some shortcomings such as poor stability and easily black-and-light lamps being scrapped early, affecting its popularization and application. The vast number of poor and middle-aged peasants are desperate to urgently solve these problems as soon as possible. This year, resolutely implementing Chairman Mao’s revolutionary line of proletarian education, he went out of school and experimented with poor middle peasants. From the physical principles of the black light lamp, we analyzed the causes and the internal causes of instability and early darkening of the lamp to find a solution to the problem The key, put forward from the converter circuit to improve the method, the line shown in Figure 2. Improved converter, lamp work totaling more than 2000 small
